Ranked in these QuestionsQuestion Ranking
Pro Free, open source and cross-platform
GIMP is completely free and open source, meaning you can use GIMP and all of its features without spending a penny. This makes it an excellent case for artists or designers who may not have the budget to spend over 700 USD on Photoshop. It is also available for free on Windows, Mac OS and Linux. It's licensed under GPL with source code available here.
GIMP is the most feature rich free image editing tool. It has most image manipulation and workflow tools that you would expect from an image editing software and what it lacks it makes up with plugins.
Pro Content-aware tools with a plugin
There's a content-aware fill plugin available for GIMP.
Pro Modular & single-window interface options
By default GIMP splits out each window, but you can check to use the one screen mode in options if you prefer.
Compared to to other photo editing software, GIMP is very light weight. In addition it isn't very resource-intensive, meaning you can put it on a flash drive and have it with you to load up on just about any computer.
Gimp has less features than programs like Photoshop, but for a beginner, or someone not needing complicated options, Gimp is the perfect choice. It allows you to quickly do basic photo manipulation so you can easily get the product you need without having to worry about complicated features getting in the way.
Pro Full channel support
Pro Lifetime updates
Pay once, get updates forever.
Pro Compatible with Photoshop PSD files
Affinity Photo can import and export .psd files.
Pro Interface will be familiar to those coming from Photoshop
The interface, especially the Photo persona, is laid out in way that's very similar to Photoshop - a panel for icons for tools on the left, a panel for information and settings on the right.
Pro Supports layer styles
Layer styles allow non-destructively applying effects to a layer.
Pro Personas allow separation of concerns
At a high level the interface is organized into broad groups of tools called Personas. Personas like Photo for in-depth image manipulation, Liquify for warping the image, Develop for basic RAW photo development and Export for exporting. Each persona displays only those tools that are needed for that task.
Pro Great performance
Uses the GPU extensively for fast speed on any platform.
Pro Powerful effects
Dozens of visual effects available. All run extremely fast with live previews
Pro Non-destructive adjustment layers
extensive adjustment layers are non-destructive.
Con Unintuitive interface
GIMP doesn't embrace OS X application design, thus Mac users might have a hard time wrapping their heads around GIMP's interface.
Con Poor performance
Con Less features than other programs
Being a free program, it shouldn't be surprising that it has limited features. For those needing more advanced features for something more professional, GIMP just isn't for you.
Con Lacks adjustment layers
Adjustment layers offer a non-destructive way of combining different photo manipulations. Without adjustment layers the only way to see changes is by irreversibly editing the image.
They are promised in future updates.
Con Limited selection of plugins
Plugin support was only recently added to AP and not many plugins have been created for the program so far.
Con Can not import gimp or krita files
Free alternatives like gimp (and krita) are sort of "go to" apps i can allways install and use for simple image editing or graphics on any computer. I find affinitys support for photoshop is great, but having support also for opening and editing gimp and krita would make the versatility and use of this program absolutely superb.
